I've been that guy who's been focused...it hurts. It's tilting. But if you look past that, you can see the light at the end of the...Nope, that's just Lux's ult. Nevermind.
The more deaths someone has in a row the less money they are worth. It's possible to be worth less money than a minion (happens at around 15-19 consecutive deaths).
Happened my last game, nobody hit the enemy Vayne with almost ALL of her teams kills. :(
I actually find it really funny when the enemy team tries their hardest to focus me, only to have it backfire and they lose the teamfight 1 for 5 lol.
